Overview
Defining the Retreat
The Great Retreat, also known as the retreat from Mons, refers to the extensive withdrawal of the British Expeditionary Force (BEF) and the French Fifth Army along the Western Front during August and September 1914. This movement was necessitated by significant defeats against the advancing German Empire forces following the Battles of Charleroi and Mons.
Timeline and Scope
The retreat commenced on 24 August 1914 and continued until the Allied forces established a defensive line along the River Marne by early September. This period was marked by continuous engagements and arduous movement, fundamentally altering the initial phase of the First World War.
Strategic Significance
This withdrawal was a critical precursor to the First Battle of the Marne. While initially a tactical defeat for the Allies, the successful continuation of the retreat and the subsequent counter-offensive prevented the swift German victory envisioned by the Schlieffen Plan, ultimately leading to the establishment of trench warfare on the Western Front.
Historical Context
The Schlieffen Plan
Germany's strategic objective was outlined in the Schlieffen Plan, which aimed for a rapid encirclement and defeat of French forces before turning attention to Russia. This plan dictated a swift advance through neutral Belgium and northern France, bypassing French border defenses.
French Strategy: Plan XVII
In contrast, French strategy, embodied in Plan XVII, focused on offensive action, particularly in the Lorraine region. This offensive posture proved insufficient against the German onslaught, contributing to the need for a strategic retreat.
Initial Engagements
The Battle of the Frontiers (August 7–13, 1914) encompassed numerous engagements along the Franco-German border and in Belgium. Early French offensives, such as the Battle of Mulhouse and the Battle of Lorraine, met strong German resistance and ultimately failed to achieve decisive results, setting the stage for the retreat.
Prelude to Retreat
Battle of Charleroi (21 August)
The French Fifth Army, positioned near Charleroi, attempted to halt the German advance. However, German forces successfully crossed the Sambre River, establishing bridgeheads. Despite French efforts, the army was unable to repel the German attacks and began a southward retirement to avoid encirclement.
Battle of Mons (23 August)
The British Expeditionary Force (BEF) engaged the German 1st Army along the Mons-Condé Canal. Outnumbered and facing flanking maneuvers, the BEF was forced to withdraw. This engagement marked the beginning of the BEF's retreat, suffering significant casualties.
The Long March South
Rearguard Actions
Throughout the retreat (24 August – 1 September), various units conducted rearguard actions to delay the German pursuit. Notable engagements included the Battle of Le Cateau, the Rearguard Affair of Le Grand Fayt, the Rearguard Affair of Étreux, the Affair of Cerizy, and the Affair of Néry. These actions, though costly, bought crucial time for the main Allied forces.
The Continuous Movement
The retreat was characterized by constant movement, often under fire, with troops covering significant distances daily. Soldiers faced exhaustion, lack of sleep, and dwindling supplies. The German pursuit, while relentless, was also stretched, impacting their operational effectiveness.
German Pursuit
The German 1st and 2nd Armies were primarily responsible for pursuing the BEF and French Fifth Army. While successful in pushing the Allies back, the pursuit was costly and sometimes disorganized, failing to achieve a complete encirclement.
Turning the Tide
The First Battle of the Marne (5-12 September)
The Great Retreat culminated in the First Battle of the Marne. A newly formed French Sixth Army, reinforced by troops moved rapidly from Lorraine, launched a counter-offensive against the German flank. This engagement halted the German advance, forcing them to retreat towards the Aisne River.
The Race to the Sea
Following the Marne, both sides attempted to outflank each other in a series of maneuvers known as the "Race to the Sea" (September 17 – October 17). This extended the front northward to the North Sea coast and led to the establishment of static trench lines.
Stalemate and Trenches
The failure of the Schlieffen Plan and the subsequent stabilization of the front marked the end of mobile warfare in the West for the duration of the war. The Great Retreat, therefore, directly led to the trench warfare that would characterize the conflict for the next four years.
Casualty Assessment
BEF Losses in 1914
The British Expeditionary Force sustained considerable casualties during the initial phase of the war, including the Great Retreat.
Comparative Losses
While specific figures vary by engagement, the battles during the retreat saw substantial losses on both sides. For instance, at the Battle of Mons, British casualties were approximately 1,642, while German losses were around 2,000. At Le Cateau, the BEF suffered around 5,212 casualties, with the Germans sustaining approximately 2,900.
